AI Technical Summary

Technical Problem

When existing drone sound wave dispersal technology is used in ancient building areas, it is easy to cause resonance and structural damage, making it difficult to meet the dual needs of tourist guidance and ancient building protection.

Method used

By adjusting the drone's position and sound wave parameters in real time, combined with the acoustic vibration response data of the ancient wall, directional interference sound waves are emitted to offset the resonant frequency, the sound wave power and period are dynamically adjusted, a three-dimensional acoustic vibration response distribution map is constructed, potential resonance areas are identified and avoided, and silent periods are inserted to reduce sound wave accumulation.

Benefits of technology

It achieves the goal of dispersing tourists while effectively reducing structural damage to ancient buildings, improving the directionality and responsiveness of sound wave intervention, and ensuring the safe protection of ancient buildings.

Abstract

A police drone sonic dispersal method, drone, product, and medium. The method includes: when tourists are detected in the dispersal area of ​​an ancient wall, obtaining the location and number of tourists, calculating the center of gravity of the tourist group, and adjusting the drone to a preset distance away from one side of the ancient wall from the line connecting the center of gravity and the ancient wall; using the line connecting the drone location and the center of gravity as the direction of sound wave emission, dynamically adjusting the sound wave emission power and period according to the number of tourists for dispersal; obtaining the acoustic vibration response data of the ancient wall under the action of sound waves, and if harmful frequency components consistent with the dangerous resonance frequency are detected, synchronously emitting interfering sound waves with the same frequency and power but opposite phase to offset the potential resonance effect. Implementation of the technical solution provided by this application takes into account the dual needs of tourist dispersal and ancient building protection.
